1) P(x) = 2x^4- 3x^3- 4x^2 + 14^x - 12. This polynomial has two rational zeroes. Use the rational root theorem and Descartes' rule of signs 1b) Write P(x) as a product of linear factors. 2). Consider the polynomial P(x)=9x^3 - 12x^2 - 20x + 16. Using the bounds theorem and rational root theorem to give a list of possible rational roots of P(x) = 0. 2b) Write P(x) as a product of linear factors. using the of Descartes' rule
